TO ALL TO WHOMl THESE PRESENTS SHALL COME:`

Be it known that I, PHILANDEP. ]IARLougiof Hudson, in the county ofMiddlesex, and State of Massachusctts,`have invented anew. and usefulMachine Belt Fastening, and do hereby declare the following to be afull, clear, and exact description thereof, reference being had to theaccompanying drawings, making part of this specification, and ,in which-Figure 1 is a top or out'er face viewcfmy invent-iones applied to abelt.

Figure 2 is a longitudinal section. of the salue; while Figure 3 is asection ot' one of its connecting plates, to be hereinafter. described.

`. The object of this invention is to produce a simple and effect-ivefastening for confining together. the ends of a machine belt or band, itbeing intended to ltake the place of the ordinary leatlfer lacings, orthe metallic clasps now in use, and which require for their applicationa number of holes to be punched in'each end ofthe belt.

The nature of the said invention, and its construction and operation',may be thus described: i

In the drawings above mentioned, A denotes a iexible metallic platefirmly secured at one extremity to the belt B4by rivets, or in anysuitable manner, and extending somewhat beyond the end of the said belt,as shown in fig. 2.I The' plate A has a central slot vor passage, a,made in it, the side-edges or Vboundaries of this slot being serrated orformed with angular teeth b b b, etc., the points of which are turnedinward toward the belt, thus forming narrow converging notches c c cAbetween them, the shape and-inclination of these teeth and notches beingshown in fig. 3 of the drawings. A. second metallic and flexible plateC, corresponding in siwzc with, or a little smaller than, the slot a ofthe plate A, is xed at both its ends to the opposite end of the belt B,which overlaps the end of the belt first mentioned, in order' that themetallic plates shall not come in Contact with the surface of the pulleyupon which the belt may be travelling., lhe plateY C overlaps one end ofthe plate A, and has two lateral projections or points cl d on itsinner'extremity, which extend underneath the plate A, or that portionofA it constituting the sides of the slot a, theV said projections d doperating witbier locking into the notches c c, etc., before referredto, and securing the two ends of the belt B together. For the purpose ofgreater security, however, the plate "C may Ahave a series of triangularteeth, e e e, etc., formed in it by making indentations in the metalcomposing it, the points of the teeth projecting inward to strikeagainstthe outer extremity of the slot a; the construction of theseteeth, as well as their connection withl the plate A, being shown ings.r1 and2 of the drawings, they being the same distance apart as theteeth 5 b b. `VTo' shorten' the belt by means of the above-describedapparatus it is only necessary to slip the projections d d of the plateC from one t' o another of the teeth I b, the distance necessary toeifeet the tightening of the belt, the strain of the belt subsequentlyserving to retract the projections into due connection with the teeth bb l, etc., f the plate 'A, and securely lock the ends of the belt inthis position.

The advantages of 'my invention, besides the fact of `enabling a belt tobe shortened 4very expeditiously, are,

that the belt s not weakened by punching a. number of holes in it as itis now the case, it being known that this is highly injurious. It isalso well known that a belt .first gives out at or near its ends, fromthis cause, and by' abrasion upon its edges against the pulley. 'Themetallic plates, of my invention, serve to protect these parts so thatthey will outwear the-rest of the belt. Furthermore, in my invention thebelt does not require to `be cut in order to shorten it, the overlappingof the. ends obviating this objection. Another objection to the oldmode,

which my invention obviates, is the fact` that the belt cannotbcshortened or taken up a little without punching new holes so near theold ones as to nearly destroy it.`

claim the belt fastening composed of the two plates A and C, constructedand operating together Vin mannerand for the purpose substantially asdescribed.
